Looks like this is something the kernel is assigning to it.  It *does*
get marked reserved:

> [    0.000000]   #6 [000009ec00 - 00000f0000]   BIOS reserved

... but that doesn't seem to keep the PCI code from assigning anything
there.  This is a Very Bad thing in general... if we're assigning
devices to areas marked reserved, we have a huge problem.
